BUILDING `CONSTRUCTION.

SPECIFICATION forming part of Letters Patent No. 766,280, dated August 2, 1904.

Application led August 31, 1903. Serial No. 171,326. (No model.)

Be it known thatI, TIMOTHY OSHEA, a citizen of the United States of America, residing at Chicago, in the -county of Cook and State of Illinois, have invented certain new and useful Improvements in Building' Constructions, of which the following is aspecitication.

illy invention relates to certain new and useful improvements in building constructions; and its object is to produce a structure which shall be strong', cheap, and easily assembled.

To this end my invention consists in certain novel features of construction, which are clearly illustrated in the accompanying drawings and described in this specification.

In the aforesaid drawings,Figure l isa view, partly in elevation and partly in section, through a building' embodying my improved construction, showing' a section through a wall, a girder, and a column. Fig'. 2 is a section in the line 2 of Fig. 1 looking downward. Fig'. 5 is a section in the line 3 of Fig.A 2 looking in the direction of the arrow. Fig. fl is a section in the line et of Fig'. 3. Fig. 5 is a section through a modified floor construetion. Fig. 6 is a section through a modified column-structure, and Fig. 7 is a perspective of the cap of one of the columns.

Referring' to the drawings, A indicates a wall, which is composed o f concrete and in which are embedded a plurality of verticallyextending' spiral strips of sheet metal A. Each of these strips is preferably about four inches wide and is twisted with a half-turn about every foot. The spiral strips, it will be seen, are spaced about eighteen inches apart and are wired togetherby wires a. This structure makes an extremely solid and rigid wall and one whose construction is extremely simple and cheap.

Transverse girders are constructed after the same manner as the walls as indicated in Figs. I and 3, the girders being' indicated by B. Horizontal strips of metal B', twisted into spirals like the strips A', are laid in tiers, the number depending upon the size of the girder. The girder shown herein is composed of six such strips laid in two rows, each three deep. These girders are wired together by wires and anchored in the walls by anchors b', passing' about the vertical strips A. Columns can be constructed following this same general com'se of construction by taking asingle strip C and embedding' it in a cylinder of concrete to form a column C. A foundation-plate c, having a groove for the reception of the lower end of the spiral strip, is provided on which the column may be supported. The cap c2 is provided at the top of the column, the spiral strips passing through a slotc in the cap and having a transverse rod or bolt c, which prevents relative longitudinal movement between the cap and the spiral strip.

Vhen it is desired to construct a larger eolumn, the method illustrated in Fig. 6 is followed, where one central spiral stripV C2 is used and a plurality of smaller strips C3, su 1'- rounding' the same. lV hen such a structure is used, the large central strip C2 passes through the cap at the top, but the smaller strips C"i terminate at the cap and aid in supporting its weight. Floors l) can be constructed from this same spiral strip and concrete structure, the spiral strips being' laid horizontally at intervals of about six inches and wired together by wires d. The ends of the strips are fiattened out at d' and curved downward at (Z2 over the edges of the girders. kind of iooring is used in connection with an I-beam construction, the same method is followed except that the ends are curved down and under the flanges of the I-bcams, as in- Y dicated at (Z3, Fig. 5, after which the entire structure is embedded in the concrete. This type of construction, it will be seen, forms a simple, strong, and easily-assembled strueture. The metal strips can be twisted up into spirals Very readily by machinery, and no difficulty is met with in working upon them in any desired way.

I realize that considerable Variation is possible in the details of this construction without departing from the spirit of the invention, and I therefore do not intend to limit myself to the specilic form herein shown and described.

I claim as new and desire to secure by Letters Patent l. In a building construction, the combination with suitable walls, g'irders and flooring', of a column comprising a concrete body and ll'hen this ICO a twisted strip of sheet metal embedded therein, a cap for the column below one of the girders, said cap being slotted for the passage of the strip of sheet metal and a cross-bar eX- tending through the strip of sheet metal and adapted to prevent a downward movement of the cap and girder uponv the strip of sheet metal.

2. In a building construction, the combination with suitable walls, girders, and floors, of a column comprising a body of concrete and a twisted strip of sheet metal of less diameter than the body of concrete and a foundationplate having a groove adapted to receive the end of the twisted sheet.

3. In a building construction, the combination with suitable walls, girders, and floors, of a Column comprising abody of concrete, a central twisted strip of sheet metal and a plurality of twisted strips arranged about said central strip.

In witness whereof I have signed the above application for Letters Patent, at Chicago, in the county of Cook and State of Illinois, this 26th day of August, A. D. 1903.
